[Translated article] Osteoporotic vertebral fractures: Natural history and impact.

Osteoporosis, and the consequences derived from it, such as fragility fractures, constitute a growing public health problem. Suffering from a fracture of this nature is the main risk factor for suffering a new fracture. It is documented that vertebral compression fractures lead to significant morbidity and mortality, in the short and long term, as well as other complications, such as sagittal imbalance and hyperkyphosis of the segment. However, we have not found documentation that analyzes the medium and long-term consequences of these injuries, assessing the type of treatment used, and the economic impact they represent. The purpose of this review is to analyse the main recent literature on the subject and make a breakdown of the consequences of these fractures in various spheres, such as economic, quality of life, sagittal balance and radiographic parameters, pain or mortality; as well as a brief analysis of epidemiology and natural history. CONCLUSION: Osteoporotic fractures constitute an emerging problem, both in the medical and economic fields. The consequences and sequelae on the patient are multiple and although surgical options offer good long-term results, it is necessary to properly select the patient, through multidisciplinary teams, to try to minimise potential complications.

[Translated article] Socioeconomic status, osteoporosis and fragility fractures.

Low socioeconomic status (SES) is associated with a higher risk of fragility fractures, as well as higher mortality in the first-year post-fracture. The SES variables that have the greatest impact are educational level, income level, and cohabitation status. Significant disparities exist among racial and ethnic minorities in access to osteoporosis screening and treatment. In Spain, a higher risk of fractures has been described in people with a low-income level, residence in rural areas during childhood and low educational level. The civil war cohort effect is a significant risk factor for hip fracture. There is significant geographic variability in hip fracture care, although the possible impact of socioeconomic factors has not been analyzed. It would be desirable to act on socioeconomic inequalities to improve the prevention and treatment of osteoporotic fractures.

Effective method of pedicle screw fixation in patients with neurologically intact thoracolumbar burst fractures: a systematic review of studies published over the last 20 years.

OBJECTIVE: To conduct a systematic review of studies on various posterior pedicle screw fixation (PSF) methods used for treating neurologically intact thoracolumbar burst fractures and to identify the most effective and safe approaches. METHODS: We conducted a systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with the study registered in PROSPERO (CRD42024531093). The inclusion criteria were: (1) publication dates from January 1, 2004, to December 31, 2023; (2) availability of full-text articles in English; (3) thoracolumbar burst fractures without neurological deficits; (4) patients aged over 18; (5) reports on treatment outcomes or complications; (6) a mean follow-up period of at least 12 months. RESULTS: A total of 69 articles covering 116 patient groups were included. Our analysis highlighted the advantages of short-segment fixation without fusion over monosegmental, short-segment and long-segment fusion in terms of shorter operation times and reduced intraoperative blood loss (p = 0.001 and p < 0.001, respectively). Extensive fusion was associated with a significantly higher frequency of deep surgical site infections compared to other PSF methods (p = 0.043). Percutaneous pedicle screw fixation, applied to patients with lower body compression rates and kyphotic deformities, led to less potential for correction (p = 0.004), yet significantly decreased blood loss (p = 0.011), operation duration (p < 0.0001), and hospitalization duration (p < 0.0001). No significant benefits were observed with the use of additional intermediate screws in short-segment PSF. CONCLUSIONS: Short-segment pedicle screw fixation could be the optimal surgical treatment method for neurologically intact thoracolumbar burst fractures. The use of posterior lateral fusion in this context may increase the deep surgical site infection rate without reducing the frequency of implant-related complications or improving long-term treatment outcomes. The percutaneous approach remains the preferred technique; however, its limited reduction capabilities should be carefully considered during surgical planning for patients with severe kyphotic deformities. The application of intermediate screws in such patients has not demonstrated significant advantages. Removing the fixation system has not led to a significant decrease in implant-related complications or improvement in quality of life. The data obtained from the systematic review may assist surgeons in selecting the most appropriate surgical treatment method for patients with neurologically intact thoracolumbar burst fractures, thereby avoiding ineffective procedures and improving both short-term and long-term outcomes.

[Translated article] Diagnostic imaging in patients with vertebral compression fractures.

Vertebral compression fractures by osteoporosis (OVF) is usually a diagnostic problem and coincides on the age group of metastatic vertebral compression fractures (MVF). Although radiography is the first diagnostic technique, generally is not accurate for depicting demineralization and soft tissue lesions. Magnetic resonance (MRI) is the diagnostic choice. The most relevant signs are intravertebral fluid collection or fluid signal, other vertebral deformities without oedema and older age. Among the most relevant findings for diagnosis MVF are soft tissue mass and pedicle intensity signal asymmetries. However, reproducibility of these findings in clinical practice is moderate.

[Translated article] Fractures of the peroneal malleolus: Current concepts.

Ankle fractures represent up to 9% of all fractures, with an increased incidence in the elderly population. Among these fractures, isolated fractures of the lateral malleolus are the most common, representing 65-70% of all cases. The therapeutic decision-making primarily relies on the stability of the ankle ring, considering it stable if affected at one point and unstable if two or more points are affected. Surgical treatment focuses on restoring the length of the fibula, joint reconstruction, stabilising the syndesmosis, and providing a stable fixation. It is crucial to rule out associated injuries that may influence therapeutic management. This article reviews the evaluation and management of lateral malleolus fractures, proposes a decision-making algorithm, and examines several fibular fixation options.

Characterization of bone disease in cystic fibrosis.

With the increased life expectancy of people with cystic fibrosis (CF), clinical attention has focused on prevention and treatment of non-pulmonary comorbidities. CF-related bone disease (CFBD) is a common complication and leads to increased fracture rates. Dual energy X-ray absorptiometry (DXA) is the recommended and gold standard technique to identify and monitor bone health. However, DXA has limitations because of its two-dimensional nature. Complementary tools to DXA are available, such as trabecular bone score (TBS) and vertebral fracture assessment (VFA). Quantitative computed tomography (QCT), magnetic resonance imaging (MRI) and quantitative ultrasound (QUS) may also be useful.

Surgical treatment of ipsilateral bifocal tibial fractures: a challenge for the surgeon. / Tratamiento quirúrgico de las fracturas bifocales ipsilaterales de tibia: un reto para el cirujano.

INTRODUCTION: The association of ipsilateral tibia fractures has a low incidence, being up to 3.2% of total tibia fractures. Currently there is no gold standard regarding the ideal surgical treatment. The objective of this study is to analyze the surgical treatment and the radiographic and functional results, as well as the associated complication rate of ipsilateral bifocal tibia fractures. MATERIAL AND METHODS: Retrospective observational study in our hospital from 2010 to 2022 of 24 patients who underwent bifocal fracture of the ipsilateral tibia. Demographic and surgical data and complications during follow-up were included. RESULTS: The 24 patients were classified into group 1 when they presented a fracture of the plateau and distal tibia (25%), group 2 with a fracture of the plateau and diaphysis (33%) and group 3 with a fracture of the diaphysis and distal tibia (42%). 3 patients underwent surgery with 1 implant and 21 patients with 2 implants. The average follow-up time in outpatient clinics was 2 and a half years. At one year, 22 patients (92%) had full weight bearing and 2 patients had partial weight bearing (8%) due to the sequelae of the fractures. The average time for consolidation of the diaphysis was 7.75±2 months, with no significant differences observed between group 2 and group 3 (p=0.06). The average time for consolidation of the metaphysis was 3.50±1.5 months, with no significant differences observed between group 1 and group 2 (p=0.065). 7 patients (30%) had complications during follow-up. CONCLUSIONS: Bifocal tibia fractures can be treated using a combination of intramedullary nailing and plate osteosynthesis with good long-term results, obtaining an optimal union rate and low complications. In addition, it facilitates the reduction of the fracture, thus facilitating the patient's recovery and obtaining good long-term functional results.

Violencia y maltrato infantil. El aporte del médico radiólogo al abordaje integral multidisciplinario / Child maltreatment and violence. Contributions from radiologists to a comprehensive multidisciplinary approach

El maltrato infantil es definido por la Organización Mundial de la Salud (OMS) como "el abuso y la desatención que sufren los niños menores de 18 años. Incluye todo tipo de maltrato físico y/o emocional […] que resulte en un daño real o potencial para la salud, la supervivencia, el desarrollo o la dignidad del niño". Al examinar los rastros corporales del maltrato físico, siguiendo los mecanismos de lesión más frecuentemente implicados, es posible detectar patrones radiológicos típicos. La evaluación imagenológica del hueso en reparación permite inferir cronologías para correlacionar con los datos obtenidos en la anamnesis. Los profesionales de la salud deben detectar oportunamente lesiones radiológicas sospechosas y activar de forma temprana el resguardo del menor. Nuestro propósito es realizar una revisión sobre las publicaciones recientes referidas al estudio imagenológico en niños de quienes se sospeche que puedan ser víctimas de violencia física.

The World Health Organization (WHO) defines child maltreatment as "the abuse and neglect that occurs to children under 18 years of age. It includes all types of physical and/or emotional ill-treatment [...], which results in actual or potential harm to the child's health, survival, development or dignity." By examining the bodily traces of physical abuse, following the most frequently involved mechanisms of injury, it is possible to identify typical radiological patterns. The imaging studies of the bone under repair allows inferring a timeline that may be correlated to the data obtained during history taking. Health care providers should detect suspicious radiological lesions in a timely manner and promptly activate the safeguarding of the child. Our objective was to review recent publications on the imaging studies of children suspected of being victims of physical violence.

Superior versus anteroinferior plating for mid-shaft clavicle fractures: a randomized clinical trial.

BACKGROUND: Clavicle fractures represent 2.5-4% of all fractures observed in emergency services. 80% occurs in the middle third. Treatment by plating requires a higher level of evidence. OBJECTIVE: To compare the functional outcomes of mid-shaft clavicle fractures managed with superior plating compared to anteroinferior plating. TRIAL DESIGN: A randomized, double-blind, parallel, superiority clinical trial. PATIENTS AND METHODS: Patients with fractures of the clavicles AO15B1 and AO15B2 were studied. Patients were randomized to be treated with either 3.5 mm superior or anteroinferior plating. A rehabilitation program was designed for both groups. The primary outcome measure was the Disability of Arm, Shoulder, and Hand (DASH) score; secondary outcomes included pain, union rate, and complication rates. RESULTS: Twenty-eight patients were studied and were eligible for analysis. Significant differences were found in the function assessed with the DASH score at 30 days for the superior plating compared with anteroinferior (43.74 vs. 29.26, respectively, p = 0.027), 60 days (23.97 vs. 11.18, p = 0.021), and 90 days (9.52 vs. 3.5, p = 0.016). One loosening with superficial infection was found with superior plating. CONCLUSIONS: Using an anteroinferior reconstruction plate in diaphyseal fractures offers better functional results than the upper plate in patients with fractures of the middle third of the clavicle.

ANTECEDENTES: Las fracturas de clavícula comprenden el 2.5-4% de todas las fracturas observadas en los servicios de emergencia. El 80% se presentan en el tercio medio. La posición de la placa como tratamiento requiere mayor nivel de evidencia. OBJETIVO: Comparar los resultados funcionales de las fracturas diafisarias de clavícula manejadas con placa superior versus placa anteroinferior. MÉTODO: Ensayo clínico aleatorizado, doble ciego, paralelo, de superioridad. Se estudiaron pacientes con fractura diafisaria de clavícula AO15B1 y AO15B2. Se manejaron con placa de reconstrucción de 3.5 mm colocada en forma superior o anteroinferior. Se diseñó un programa de rehabilitación para ambos grupos. El resultado primario fue medido con el cuestionario DASH y los resultados secundarios incluyeron dolor, presencia de consolidación y complicaciones. RESULTADOS: Fueron elegibles para análisis 28 pacientes. Se encontraron diferencias significativas de la escala DASH a los 30 días para la maniobra superior comparada con la inferior (43.74 vs. 29.26, respectivamente; p = 0.027), a los 60 días (23.97 vs. 11.18; p = 0.021) y a los 90 días (9.52 vs. 3.5; p = 0.016). CONCLUSIONES: El uso de placa de reconstrucción anteroinferior en las fracturas diafisarias ofrece mejores resultados funcionales en comparación con la placa superior en pacientes con fracturas de tercio medio de clavícula.

[Frailty, Sarcopenia and Osteoporosis]. / Fragilidad, sarcopenia y osteoporosis.

Frailty, sarcopenia and osteoporosis are entities specific to the elderly, who share some risk factors. For this reason, their relationship has been studied in different works, which have provided disparate results, probably because these studies have not always focused on the same aspects. This article reviews the relationship of frailty and sarcopenia with osteoporosis.

Seguimiento a muy largo plazo tras implante de stent en la coartación de aorta / Very long-term follow-up after aortic stenting for coarctation of the aorta

Introducción y objetivos: El implante de stent es el tratamiento de elección en niños mayores y adultos con coartación aórtica (CoA). El objetivo fue determinar la incidencia de eventos tardíos después del tratamiento con stent. Métodos: Se analizó una cohorte de pacientes con CoA tratados en el centro entre 1993 y 2018 a los que se siguió periódicamente, incluyendo evaluación mediante tomografía computarizada (TC) y fluoroscopia. Resultados: Se incluyó a 167 pacientes con TC y fluoroscopia: 83 (49,7%) ≤ 12 años y 46 (28%) mujeres. El tiempo medio de seguimiento clínico fue de 17±8 años (rango 4-30) y de 11±7 años hasta la TC/fluoroscopia. Se detectó aneurisma en un 13% y se asoció al stent PALMAZ (OR=3,09; IC95%, 1,11-9,49; p=0,036) y a la longitud del stent (OR=0,94; IC95%, 0,89-0,99; p=0,039). La fractura del stent fue frecuente (34%) pero no asociada a la presencia de aneurisma. Se asoció con edad joven (OR=3,57; IC95%, 1,54-8,33; p=0,003), sexo masculino (OR=4,00; IC95%, 1,51-12,50; p=0,008) e inversamente con el stent PALMAZ (OR=0,29; IC95%, 0,12-0,67; p=0,005). La reintervención fue menor en adultos (10%), principalmente por aneurismas. Los pacientes que recibieron tratamiento cuando tenían 12 años o menos presentaron tasas de reintervención más altas (43%) debido al crecimiento somático. Conclusiones: Se observó una incidencia notable de eventos tardíos a largo plazo en pacientes con CoA tratados mediante stent. La reintervención fue más frecuente en pacientes tratados a edades más jóvenes. Parece aconsejable una vigilancia periódica mediante pruebas de imagen. (AU)

Introduction and objectives: Stent implantation is the preferred treatment in older children and adults with aortic coarctation (CoA). We aimed to determine the incidence of very late events after CoA stenting. Methods: We analyzed a cohort of CoA patients who underwent stent implantation at our center between 1993 and 2018. Patients were periodically followed up in outpatient clinics, including computed tomography (CT) and fluoroscopy assessment. Results: A total of 167 patients with CT and fluoroscopy data were included: 83 (49.7%) were aged ≤ 12 years and 46 (28%) were female. The mean clinical follow-up time was 17±8 (range 4-30) years and the mean time to CT/fluoroscopy was 11±7 years. Aortic aneurysm was present in 13% and was associated with the PALMAZ stent (OR, 3.09; 95%CI, 1.11-9.49; P=.036) and the stented length (OR, 0.94; 95%CI, 0.89-0.99; P=.039). Stent fracture was frequent (34%), but was not related to the presence of aneurysm. Stent fracture was associated with young age (OR, 3.57; 95%CI, 1.54-8.33; P=.003), male sex (OR, 4.00; 95%CI, 1.51-12.5, P=.008) and inversely with the PALMAZ stent (OR, 0.29; 95%CI, 0.12-0.67, P=.005). Reintervention was lower in adults (10%), mainly related to aneurysms. Those treated when aged ≤ 12 years had higher reintervention rates (43%) due to recoarctation somatic growth. Conclusions: This long-term follow-up study of CoA patients treated with stenting revealed a significant incidence of late events. Reintervention rates were higher in patients treated at younger ages. Periodic imaging surveillance appears to be advisable. (AU)

[Cost-effectiveness analysis of fracture liaison services in Catalonia]. / Análisis de coste-efectividad de las Unidades de Coordinación de Fracturas en Cataluña.

OBJECTIVE: To assess the cost-effectiveness of Fracture Liaison Service (FLS) compared to the standard of care for secondary prevention of fragility fractures form the perspective of the Catalan Health Service. METHODS: Cost-utility assessment through a Markov model that simulated disease progression of a patients' cohort candidates to initiate antiosteoporotic treatment after a fragility fracture. A time horizon of 10 years and a 6-month duration per cycle was established. Clinical, economics and quality of life parameters were obtained from the literature and derived from four Catalan FLS. The Catalan Health Service perspective was adopted, considering direct health costs expressed in 2022 euros. A 3% discount rate was applied on costs and outcomes. Uncertainty was assessed through multiple sensitivity analyses. RESULTS: Compared to the standard of care, FLS would promote antiosteoporotic initiation and persistence, reducing the incidence and mortality associated with subsequent fragility fractures. This incremental clinical benefit was estimated at 0.055 years and 0.112 quality-adjusted life years (QALYs) per patient. A higher cost (€1,073.79 per patient) was estimated, resulting into an incremental cost-utility ratio of €9,602.72 per QALYs gained. The sensitivity analyses performed were consistent, corroborating the robustness and conservative approach of the base-case. CONCLUSIONS: The introduction of FLS for the secondary prevention of FF would represent a cost-effective strategy from the Catalan Health Service perspective.

INTRODUCTION Distal femoral fractures (DFF) are a relevant problem for public health worldwide. As the population ages, an increase in the rate of these lesions is expected in the next few years. Objective To describe the complications and mortality from DFF in geriatric patients. MATERIALS AND METHODS A descriptive and retrospective study with patients aged 60 years or older who underwent surgery due to DFF. All subjects received treatment in the same trauma center from 2011 to 2015 and underwent a minimum follow-up of 1 year. Patients with incomplete medical records were excluded. We analyzed demographics, radiological findings, local and systemic complications, length of stay, and mortality rates. RESULTS In total, 16 patients met the inclusion criteria; their median age was of 72 (range: 61 to 93) years, and 14 subjects (87,5%) were female. The classification of the Association for the Study of Internal Fixation (Arbeitsgemeinschaft für Osteosynthesefragen, AO, in German) was as follows: A ­ 12 patients (75%); B ­ 2 patients (12.5%); and C ­ 2 patients (12.5%). There were no open fractures. The devices used in the operations included dynamic condylar screw (DCS) plates (9 subjects; 56%), distal femur locking compression plates (LCPs) (4 subjects; 25%), and retrograde distal femoral nails (DFNs) (3 subjects; 19%). The median time until surgery was of 10 (range: 3 to 27) days, with a median length of stay of 14 (range: 5 to 47) days. Complications were presented by 6 (37.5%) patients: 2 (12.5%) cases of pulmonary thromboembolism and 4 (25%) cases which required reintervention (2 due to hardware failure, 1 because of arthrofibrosis, and 1 due to aseptic nonunion); there were no cases of infection. The mortality rate at 12 months was of 0%. CONCLUSION The patients with DFF in this geriatric cohort presented a long length of stay, with a high rate of complications, including a rate of 25% of reintervention. Nevertheless, the 1-year mortality rate was of 0%

Hidden blood loss in minimally invasive surgery for osteoporotic vertebral fractures. / [Artículo traducido] Sangrado oculto intraoperatorio en cirugía mínimamente invasiva de fracturas vertebrales osteoporóticas.

INTRODUCTION AND AIM: Minimally invasive surgery (MIS) of the spine prevents the collapse of osteoporotic vertebral fractures (OVF) with lower complication and bleeding rates than open surgery. However, the possibility of hidden blood loss (HBL) has been recently described, referring to the loss of blood diffused into tissues and lost through hemolysis. This study aimed to estimate the postoperative impact of HBL in patients undergoing MIS for OVF. MATERIALS AND METHODS: This was a retrospective study of a series of patients who had MIS for OVF. A descriptive analysis of recorded variables was performed, and total blood volume, total bleeding, HBL, and hemoglobine drop were calculated. This was followed by a comparative analysis between HBL (<500ml vs. ≥500ml) and the variables of hospital stay and postoperative evolution. Binary logistic regression models were performed to rule out confounding factors. RESULTS: A total of 40 patients were included, 8 men and 32 women, with a mean age of 76.6 years. The mean HBL was 682.5ml. An HBL greater than 500ml is found to be an independent risk factor for torpid postoperative evolution (P=0.035), while it does not predict a longer hospital stay (P=0.116). In addition, a higher HBL was observed in surgeries of greater technical complexity and longer surgical time. CONCLUSIONS: Although MIS techniques have shown less intraoperative bleeding than open surgery, HBL should be diagnosed because it is associated with a torpid evolution. The use of a diagnostic and therapeutic algorithm may help minimize its impact.

[Translated article] Spinopelvic dissociation: Current concepts.

INTRODUCTION: Spinopelvic dissociation is an uncommon injury, but, at the same time, very serious, since it can associate important complications with high morbidity and mortality. Its low frequency means that the experience of the specialists who have to deal with it is often very limited. OBJECTIVE: To analyze the treatment indications based in classifications and surgery techniques. METHOD: A search for scientific articles from high-impact journals was performed through international databases, such as Pubmed, Cochrane Library, Scopus, Science Direct and OVID. CONCLUSIONS: The management of the injury we are analyzing represents a challenge. The diagnosis is carried out through a meticulous anamnesis and physical examination, supported by imaging tests, where tomography acquires special relevance. The treatment is fundamentally surgical, reserved the conservative option for a few cases. Triangular fixation is nowadays considered the treatment of choice.

Efecto del shiatsu sobre el dolor en personas con fracturas de extremidades: ensayo clínico / Efeito do shiatsu sobre a dor de pessoas com fraturas nos membros: ensaio clínico / Effects of shiatsu on pain in people with limb fractures: clinical trial

The postoperative period for limbs fractures is characterized by different levels of pain intensity. Shiatsu is a therapy applied with the hands on meridians and tsubos (points similar to acupuncture) related to pain. Objective: To evaluate the effect of shiatsu on postoperative pain in men with arm and leg fractures. Method: Non-randomized and uncontrolled clinical trial, with assessment of pain levels using the Visual Numerical Scale (VNS) (0­10) and measurement of salivary cortisol. The R software and the Wilcoxon test and Fisher's exact test were used. Results: 41 people participated in the research; the initial mean value of salivary cortisol concentration was 0.39 µg/dl and, after shiatsu intervention, it decreased to 0.32 µg/dl (p<0.0001). The Mean pain value was 4.93 (VNS) before the intervention and 3.90 (p<0.0001) after. Conclusion: The application of shiatsu contributed to reducing pain and cortisol levels in people undergoing orthopedic surgery. (AU)

El valor promedio del dolor fue de 4,93 (ENV) antes de la intervención y de 3,90 (p<0,0001) después de la intervención. Conclusión: La aplicación de Shiatsu contribuyó a reducir el dolor y los niveles de cortisol en personas sometidas a cirugía ortopédica. (AU)
